There is a subclinical decrease in right ventricular systolic and diastolic echocardiographic indices, although mostly, in the normal range, in a relatively short time interval after onset of chemotherapy.
ObjectiveThe role of systemic and chronic inflammatory processes in the pathophysiology of rheumatic heart valve disease is well known. The neutrophil-to-lymphocyte ratio (NLR) was shown to be an indicator of systemic inflammation. In this study, we aimed to investigate relationship between NLR as a marker of systemic inflammation and rheumatic mitral valve stenosis (RMVS).MethodsThis is a retrospective study. Among patients who underwent transthoracic echocardiography between January 2008-March 2013, 314 patients with RMVS were included retrospectively in the study. The control group included 57 healthy persons who underwent transthoracic echocardiography during the study period. Basal characteristics and NLR were compared between the two groups. Independent predictors of RMVS were determined by logistic regression analysis.ResultsBasal characteristics were similar among the groups (age, 50.2±14.2 vs. 49.2±13.0, p=0.60). The NLR was significantly higher in patients with RMVS [2.9 (0.6-13.0) vs. 2.1 (0.7-5.8), p<0.001]. Besides, C-reactive protein (CRP) was also higher in the RMVS group [5.99 (0.3-23.7) vs. 2.98 (0.6-6.3), p=0.001]. In the regression analysis, NLR (OR: 2.24, p=0.04), CRP (OR: 1.34, p=0.03), and left atrial diameter (OR: 1.21, p=0.001) were independent predictors of RMVS. In the correlation analysis, there was a significant positive correlation between NLR and CRP (r=0.43, p<0.001).ConclusionWe found that NLR was significantly increased in RMVS. Furthermore, NLR was an independent predictor of the presence of RMVS in our study population. According to these findings, NLR can be used as a predictor of RMVS. Since it is an easily available and cheap method, it can easily be used in daily clinical practice. Increased NLR can also be a sign of ongoing chronic inflammation in patients with RMVS.
OBJECTIVE: Recent studies have linked malnutrition with undesirable outcomes in cardiovascular diseases. However, the underlying mechanism is unknown. Contrast-induced acute kidney injury (CI-AKI) increased cardiovascular mortality after percutaneous coronary intervention (PCI). This study hypothesizes that prognostic nutritional index (PNI) plays a role in the development of CI-AKI in patients with acute coronary syndrome undergoing emergency PCI.METHODS: This study enrolled 551 patients. PNI was determined as 10× serum albumin (g/dL)+0.005×total lymphocyte count (mm³).CI-AKI was characterized as the increase in serum creatinine ≥0.3 mg/dL level within 48 h after PCI. Patients were classified as either
CI-AKI (+) or CI-AKI (−).RESULTS: CI-AKI has occurred in 72 of 551 patients (13.1%). PNI was significantly lower in the CI-AKI (+) group than in the CI-AKI (-) group (44.4±6.6 versus 47.2±5.8, p<0.001, respectively). Multivariate logistic regression analysis showed that PNI [odds ratio, OR: 1.631, 95% confidence interval (CI): 1.168-2.308, p=0.02] and estimated glomerular filtration rate (OR: 3.26, 95%CI 1.733-6.143, p<0.001) were independent risk factors for CI-AKI.CONCLUSIONS: PNI is an independent risk factor for CI-AKI. The development of CI-AKI may be the mechanism responsible for the relationship between poor nutritional status and adverse cardiac events.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
